General Purpose (GP) Highway Lanes General Purpose facilities are highway lanes that allow unrestricted, non-tolled use by all vehicles. All Chicago-area expressways are currently. GP lanes except the tolled Chicago Skyway and Illinois Tollway facilities. GP Highway lanes can carry up to 2000 vehicles per hour. www.dot.il.gov www.eisenhowerexpressway.com Page 10.» Express bus service can be considered if shoulder riding is allowed, otherwise it cannot be reliably scheduled in congested conditions.» GP lanes do not offer congestion-management strategies other than additional lane capacity.

High Occupancy Vehicle (HOV) Lanes High Occupancy Vehicle (HOV) facilities are highway lanes that allow priority access by vehicles that have two or more riders, such as carpool, van or bus. Single occupant vehicles are not permitted. Carpool vehicles have a minimum of two (2+) and sometimes three (3+) or four (4+) occupants. Express bus service can also use HOV lanes; usually not considered true BRT (Bus Rapid Transit) as it is not a Bus Only lane. Use of HOV lanes does not require a toll. Some HOV s also allow hybrid vehicles with single occupants. www.dot.il.gov www.eisenhowerexpressway.com Page 11» Painted buffer allows easier access between GP lanes and HOV lanes.» Barrier separated HOV lanes require more width, but offer better traffic control & channelization.» Enforcement of painted buffer HOV more difficult than barrier separated HOV.» With painted HOV buffers, traffic incidents in GP lanes can negatively affect HOV lane operations. Barrier separation reduces these affects.» Barrier separation can complicate snow removal operations.» Existing lanes can be converted to HOV with little or no additional right-of-way.» Adding new HOV lanes to existing GP lanes may require additional ROW.

High Occupancy Toll (HOT) Lanes High Occupancy Toll (HOT) facilities are highway lanes that allow priority use to High Occupancy Vehicles (HOV) such as carpool, van or bus, as well as Single Occupant Vehicles (SOV) with selectively applied tolls. Congestion based pricing can be used to maintain acceptable levels of service for HOT lane users (example LOS C or better). Express Bus service can also use HOT lanes; usually not considered true BRT (Bus Rapid Transit) as it is not a Bus Only lane. HOT lanes apply tolls on some or all vehicles, with SOV s and trucks (if allowed) paying highest tolls. www.dot.il.gov www.eisenhowerexpressway.com Page 12» Painted buffer allows easier access between GP lanes and HOT lanes.» Barrier separated HOV lanes require more width, but offer better traffic control & channelization.» Enforcement of painted buffer HOT more difficult than barrier separated HOT.» With painted HOT buffers, traffic incidents in GP lanes can negatively affect HOT lane operations.
